Answer:


Step-by-step explanation:

1. The given equation is:

\frac{3}{5}{\times}\frac{4}{5}

Multiplying both the terms, we get

\frac{12}{25}

Option A is correct.

2. The given equation is:

2\frac{1}{3}{\times}\frac{3}{4}

Converting the improper fraction into the mixed fraction,

\frac{7}{3}{\times}\frac{3}{4}

=\frac{7}{4}

Option C is correct.

3. The given equation is:

\frac{3}{16}{\times}\frac{4}{21}

Multiplying both the terms, we get

=\frac{1}{28}

4. The given equation is:

3\frac{8}{9}{\times}4\frac{4}{5}

Converting the improper fraction into the mixed fraction,

\frac{35}{9}{\times}\frac{24}{5}

=\frac{56}{3}

5. One package contains= 5\frac{1}{4}=\frac{21}{4} pounds of raisins.

4\frac{2}{3} packages contains=4\frac{2}{3}{\times}5\frac{1}{4} pounds of raisins.

=\frac{14}{3}{\times}\frac{21}{4}

=\frac{49}{2}

Therefore, the baker used \frac{49}{2} pounds of raisins.

In a first-order decomposition reaction. 52.3% of a compound decomposes in 8.6 min. How long (in min) does it take for 80.3% of
rusak2 [61]

Answer:

13.20 min

Step-by-step explanation:

Rate of the reaction is a measure of the rate of decomposition of the compound.

Rate (R) = Concentration (C) ÷ time (t)

C1/t1 = C2/t2

C1 = 52.3% = 0.523

t1 = 8.6 min

C2 = 80.3% = 0.803

t2 = C2t1/C1 = 0.803×8.6/0.523 = 13.20 min (to 2 decimal places)

Write a function that models each variation.
Leno4ka [110]

Answer:

z = 2.7x/r²y

Step-by-step explanation:

z = kx/r²y

½ = k × ⅓ ÷ (3² × ⅕)

½ = ⅓k × 5/9

k = 27/10 = 2.7

z = 27x/10r²y

z = 2.7x/r²y
